        摘 要:針對目前配電網異常用電行為精度欠佳、效率低下、人力資源耗費量大等問題,在海量用電數據中利用數據挖掘技術實現異常用電數據的精確查找與定位。通過引入社群習慣的行業季節用電水平等異常分類指標,對可能存在非技術性損耗(NTL)的配網用戶進行分析和檢測,利用改進粒子群LM 神經網絡算法建立了有效的異常用電行為的自動識別模型。實驗結果表明:該模型能夠有效地提取用電特征,實現對異常用戶的檢測,具有較強的識別能力和較高的實用性。

         Abstract: In order to solve the problem of poor accuracy, low efficiency, and high consumption of human resources in abnormal power consumption of power distribution network, this paper used data mining technology to accurately locate abnormal power consumption data in magnanimity power utilization data. The network users who might have non-technical loss (NTL) were analyzed and detected by using the industry's seasonal power consumption level of the community's habits and other abnormal classification indicators. The improved particle swarm LM neural network optimization algorithm was utilized to establishe an effective automatic recognition model for abnormal power consumption. The experimental results show that this model can effectively extract the electricity characteristics and realize the detection of abnormal users with strong recognition ability and high practicability.
        Key words: abnormal power consumption; non-technical loss; community feature; improved particle swarm optimization
